For the purpose of coating the mal size to closely fit over and hug the roll proper, rolls with glue, I provide a machine of the conand wherein the covering is secured on the roll struction shown in Figures 1 to 5 inclusive. This 15 y proper by means of glue with which the roll machine consists of atank Tprovided with corner proper is coated preparatory to application of the supporting legs L and adapted to be substantially covering thereon. lled with hot water.

Figure '7 is an enlarged perspective view of the In order to keep the water in the tank T at 55 the proper temperature to insure maintenance of the glue in the troughs 1 in the proper uid or melted state, a suitable electric or other heater 2l is arranged beneath said tank T and supported upon a platform 22 carried by a frame 23 connecting the lower ends of the legs L. A suitable faucet 24 is provided at one end of the tank T to facilitate draining of the water therefrom, and similar faucets 25 are provided at the same end of the machine to facilitate draining of the glue from the troughs l if found necessary. The tank T may be provided at one side with a suitable spout 2B to facilitate replenishing the supply of water in the tank T from time to time when found necessary, said spout having a hinged gravityclosed lid 2 which will permit free escape of steam from the tank T in case the water therein should be overheated.

In operation, the rolls 5 to be coated are laid upon the coating rollers 8 at the point where they adjoin, as shown in Figures 1 and 5. The motor i8 is then placed in operation so as to rotate the rollers 8 in the melted glue contained in the lower portions of the troughs l. In this way, the rollers 8 become coated with the glue and transfer the same onto the peripheries of the rolls 5 while the latter are being rotated through frictional contact with the rollers 8. Thus, a uniform coating of glue is applied to the rolls 5.

The present invention also includes a metal tube 28 provided at one end with an external annular flange 29, and the tube 28 is of an internal size slightly greater than the external diameter of the rolls 5 to be covered. The seamless elastic tubing 6 is adapted to be stretched and fed onto the tube 28 with one end of the elastic tubing abutting the flange 29. The elastic tubing is bunched on the tubing 28 so that suiTicient elastic tubing is contained thereon to cover a plurality of the rolls 5, as illustrated somewhat diagrammatically in Figure 6 Naturally, when the tubing 8 is placed on the tube 28, it is stretched so that application of the covering to the rolls 5 may be conveniently accomplished. The coated rolls 5 are inserted in the tube 28 through the flanged end thereof, and as the end of each roll 5 protrudes at the unflanged end of the carrier tube 28, such end and the adjacent end of the covering or tubing 6 is grasped by contact with such tubing 6 and pulled outwardly through the tube 28. As the roll 5 is withdrawn, the tubing 6 is pulled off of the carrier tube 28 and allowed to contract into snug engagement with the roll 5. Suicient tubing E is allowed to project beyond the ends of the roll 5 to facilitate finishing at the ends as disclosed in my above-mentioned application, whereupon the tubing 6 is out off ready for the next operation of covering the succeeding roll 5. Naturally, when the glue hardens, the covering is firmly secured on the periphery of the roll 5 in an unwrinkled condition, and the covering operation has been accomplished with a minimum handling of the roll proper 5 after being coated with glue.

From the foregoing description, it is believed that the nature and advantages of the present invention will be readily understood and appreciated by those skilled in the art.

What I claim as new is:

A-portable apparatus for coating clearer rolls with glue preparatory to application of a covering thereon, comprising a rectangular water tank having a filler spout and provided with corner supporting legs, twin glue-containing troughs arranged within the upper portion of said tank,

glue-applying rolls arranged in Said troughs and disposed in adjacent relation with the space therebetween less than the diameter of the clearer rolls to be coated, a rectangular frame connecting said legs beneath said tank and carrying a platform, heating means for said tank arranged on said platform, driving means at one end of said tank for simultaneously rotating said glue-applying rolls in the same direction, said driving means including a motor arranged on one end of said platform and geared to the adjacent ends of said glue-applying rolls, and drain faucets for said tank and said troughs at the ends thereof remote from said driving means.
